Lockout/Tagout Annual Audit Requirements: What OSHA Expects
Under OSHA 1910.147(c)(6), every energy control procedure in your program must be inspected at least once a year. This "periodic inspection" is the audit trail that proves your LOTO program works in practice, not just on paper — and skipping it is one of the most frequently cited violations of the standard.
What gets inspected
The inspection reviews each energy control procedure for the equipment it covers: are all energy sources identified, are isolation points correct, do the steps match what employees actually do, and are stored-energy and verification steps adequate? The inspector also reviews with each authorized employee their responsibilities under the procedure, and with affected employees the prohibitions against operating locked-out equipment.
Who can perform the inspection
It must be performed by an authorized employee — someone trained in LOTO — other than the employees who use the procedure being inspected. In practice this means a supervisor, safety manager, or peer from another shift or site. You cannot self-audit your own procedure.
The certification you must keep
The employer must certify that the inspections were performed. The certification must identify the machine or equipment, the date of the inspection, the employees included, and the person performing the inspection. If your site has 40 LOTO procedures, you need 40 certified inspections every year. These records are among the first things an OSHA inspector asks for.
What happens when deviations are found
If the inspection finds that employees are deviating from the procedure — or the procedure itself is wrong — corrections must be made before work continues under it. The affected employees must be retrained where needed. Findings and corrections are part of your program record.
How digital tools make annual audits manageable
Tracking 40 or 400 annual inspections with spreadsheets invites missed deadlines. Digital LOTO platforms can track inspection due dates per procedure, record who reviewed what and when, store the certification automatically, and surface deviations to fix — turning the annual audit from an annual scramble into a routine report.
Key takeaways
- Every procedure, every year — no exceptions or grace periods.
- The inspector must be authorized but not a user of that procedure.
- Certification must name the equipment, date, employees, and inspector.
- Deviations require correction and possible retraining before continued use.
Frequently asked questions
Does the annual inspection cover tagout procedures too?
Yes. Tagout procedures get the same annual inspection, plus a required additional review with each authorized employee of the extra safety measures used in place of a lock.
How long should we keep inspection records?
OSHA does not set a fixed retention period for the certification itself, but the current certification is what must be available on request, and most auditors expect multi-year records as evidence of a consistent program.
Can two procedures be inspected at the same time?
Each energy control procedure needs its own inspection and its own certification. Reviewing ten procedures in one session is fine — certifying them on one form is not.
